Once a demon be witched a tarantula, that whom thirst were to be bit by the tarantula would becom her demon child forever.

Years past and the tarantula got big and one day a little girl pickt it up with no fear in her vains but she got bit,doctors and priests tried to heal her but nothing worked after a time the girl started to transmutate in to the demon child.
The priests tride to get the demon out of her but nothing worked and thay had to ban her to the underground.
Now she lives there on eat the corps of dead miners and other creatures that come in her way.
She will never be a full demon but she will never becom a human again.
